DATE: Tuesday 7th May, 2024 CLASS: Year 5 SUBJECT: Social Studies TOPIC: Savings (Capital resources preservation) Meaning of Saving Saving is the process of keeping things, money and other material resources for future use. Bank is a financial institution where money and other valuable items (gold, documents and certificate) are kept for future use. One can withdraw his or her money(savings) from the bank either through the counter by using a withdrawal slip or through a dispensing machine known as ATM (Automated Teller Machine). The following are the importance of savings: 1) To meet future needs. 2) To protect our resources (money, gold) from being stolen. 3) To build houses. 4) To make it possible to borrow large amounts of money. 5) To earn interest or profit on it. PAST (OLDEN DAYS) WAYS OF SAVING: i) Under the bed ii) Under the ground of the house. iii) Rooftops iv) Shrines v) Secret places like under the rocks. vi) Trunks and hollows of trees. MODERN WAYS OF SAVING ARE: i) In the bank ii) Inside a piggy bank iii) Through Cooperative Societies iv) Through Insurance companies v) Through Mortgage houses vi) Thrift and Credit societies. CAUSES OF POOR SAVINGS ARE AS FOLLOWS: i) Bad economy and decrease in the standard of living in our society. ii) Inability to manage income properly. iii) High level of spending iv) Having too many financial obligations or responsibilities.

THE SOAR SYSTEM A solar system is a group of planets and other celestial bodies that revolve around a star. A solar nebula- a vast cloud of gas and dust, mostly hydrogen and helium. How the Solar System Form • COLLAPSE AND SPINNING DISK FORMATION - Gravity pulls material inward. The cloud flattens into a spinning disk due to conservation of angular momentum. • PROTOSTAR FORMATION- (BIRTH OF THE SUN). Material collects at the center, and begun to heat up. When it reaches to 10 million KELVIN, nuclear fusion begins. thus, SUN is born. • PLANETESIMALS AND PROTOPLANETS. Dust and gas in the disk stick together via static and gravitational forces. These form planetesimals, which grow into protoplanets collision and accretion. • PLANET FORMATION. Inner disk: too hot for gas rocky planets form Mercury, Venus, Earth, Mars. • PLANET FORMATION. Outer disk: gas and ice giants. Jupiter, Saturn, Uranus, Neptune • LEFTOVER DEBRIS. Remaining materials forms moon, asteroids, comets and dwarf planets. DIFFERENT HYPOTHESIS IN THE FORMATION OF SOLAR SYSTEM. 1. NEBULAR HYPOTHESIS- The Solar system formed from a rotating cloud of Gas and Dust (solar nebula). As it rotates conservation of angular momentum caused the cloud to flatten into a disk. the Sun formed at the center (DISK) while planets formed from the surrounding materials through acceleration. thus, it explains the coplanar and nearly circular orbit of the planets all planets orbits around the sun on the same flat, disk shaped plane. Proposed by Immanuel Kant in 1755 and Modified by Pierre Simon Laplace in 1756. PROTOPLANET HYPOTHESIS. The Solar system formed from a rotating cloud of Gas and Dust (solar nebula). As it rotates conservation of angular momentum caused the cloud to flatten into a disk. 2. Protoplanet hypothesis. Builds on the nebular model but focuses more on the role of planetesimals which then form into full planets. PROCESS: - Small solid particles stick together through collisions. As collisions takes place, it grows into kilometer-sized planetesimals. Gravitational interactions lead to the formation of planets. Lead to formation of steroids belts and varying planet sizes 3. Encounter hypothesis. States that the sun encountered a rogue star. The encounter led to the removal of hot gas from both stars due to their gravitational interaction. The hot gas then accumulated and formed the planets. The materials from the less dense rogue star formed the other planets, while that from the sun formed the inner planets. 4. TIDAL HYPOTHESIS. (also called the Tidal Theory) is an early scientific idea about how the solar system might have formed. Proposed by James Jeans and Harold Jeffreys. A massive star passed very close to the early Sun. The hot gas then accumulated and formed the planets. The materials from the less dense rogue star formed the other planets, while that from the sun formed the inner planets. Streams of hot gas were drawn out from the Sun in elongated shape. These streams eventually condensed and cooled, forming planets, moons, and other bodies in the solar system. 5. Not accepted theory. Later studies showed the streams of hot gas would disperse too quickly into space instead of condensing into planets. The theory also couldn’t explain the specific orbital patterns and compositions we see today. Modern science favors the Nebular Hypothesis, which explains solar system formation through the collapse of a rotating gas cloud. Earth as the only habitable planet 1. Right Distance from the Sun (The Goldilocks Zone). Not too hot, not too cold — just right for liquid water to exist. 2. Atmosphere with Oxygen. Earth has a mix of gases, especially oxygen, which most living things need to survive. 3. Liquid Water. Earth has oceans, rivers, and rain — water is essential for all life. 4. Magnetic Field. Earth’s magnetic field protects us from harmful solar radiation. 5. Stable Climate. The atmosphere and natural cycles keep temperatures and weather mostly stable over time. 6. Rich Resources. Earth has soil for growing food, minerals, and energy sources that support life and technology. Solar explorations 1. AUGUST 6, 2014. First space craft to orbit a comet (ROSETTA PROBE).

Quiz 2: Earth’s Resources and the Rock Cycle

If we look at the United States on a map today, it is very difficult to imagine that where we see borders, cities, and states, there once existed nothing but open land, uncharted mountain ranges, and miles of untouched wilderness. North America was a highly desired destination for exploration and settlement for Europeans. In the early 1500s, expeditions from Europe to North America were funded by Europe's kings and queens in hopes of expanding their territories across the world. The voyages were treacherous with unknown dangers and many attempts to settle in this new land were faced with failure. In the early 1600’s however, the settlers of Jamestown and Plymouth survived the harsh conditions and established the first two permanent English settlements in North America. Jamestown Colony in Virginia Jamestown was founded in 1607. Of course, its colonists did not know it would go on to become the the first permanent English settlement in the Americas. The settlement was located along the James River off Chesapeake Bay in modern-day Virginia. Life in Jamestown was very hard, and nearly 80% of the first settlers died in the first year due to disease and starvation. The region was warm and had fertile soil, making it a perfect place for growing crops, specifically tobacco. Sponsored by a joint stock company known as the Virginia Company of London, Jamestown was originally established as a profit-making enterprise. The first settlers looked for gold and other natural resources that could bring a profit to the company's investors. After several very difficult years, the colonists were eventually able to grow tobacco that was popular in England and it became a valuable cash crop. Jamestown's colonists were primarily all supporters of the Church of England and felt a strong connection to their homeland. Many, like John Smith, returned to England, or would move back and forth between the two locations. Being that Jamestown was founded by a corporation looking to make a profit, it began using enslaved labor in 1619. Indentured servants and enslaved Africans made up much of the workforce on the growing tobacco and cotton plantations. The system of using enslaved Africans for the profit of American plantations has been described as America's "original sin". About 400 miles to the north of Jamestown, a group of Pilgrims seeking religious freedom established Plymouth in 1620 as the second English colony in North America. Located in modern day Massachusetts, the colder climate and rocky soil made farming and agriculture more difficult. Instead of growing cash crops, settlers turned to lumber, shipbuilding, and fishing for trade. Unlike the settlers of Jamestown, the Pilgrims of Plymouth Colony were dissenters from the Church of England. They came to the New World so that they could freely practice their religion without fear of persecution. Although their reasons for settling were different, the settlements had many similar experiences. Jamestown and Plymouth both faced harsh and demanding climates and struggled with hunger, disease, and death. In their first years they had much difficulty establishing housing and finding a sustainable source of food. Plymouth Colony in New England While the settlers in Jamestown used the House of Burgesses as a legislative body for laws and decisions, the Pilgrims in Plymouth wrote and agreed to the Mayflower Compact as a set of rules for self-government. Both helped maintain the rule of law in new places far from the courts and tradition of England. Settlers of both colonies experienced complicated and, at times, violent relationships with local Native Americans that owned the land. While some American Indian groups offered help to the new settlers, oftentimes both sides needed to defend themselves from attacks. Nevertheless, the settlers of Jamestown and Plymouth persevered through these difficulties and maintained their establishments, providing inspiration for future colonies and settlers in search of a new life in the New World.
